The average cost of a lithium-ion (Li-ion) battery cell will fall below $100 per kilowatt hour (kWh) in the next three years, according to a new analysis by IHS Markit. The average cost of a li-ion cell is expected to decline further through the end of the decade, to as low as $73/kWh in 2030.
The average cost of a lithium-ion (Li-ion) battery has already fallen 82% from 2012-2020. Further reductions are a key factor to increasing the competitiveness and wider adoption of the batteries for electric transportation and in grid storage. By 2023, the cost of a battery will have declined 86% (by $580/kWh) in a decade, according to the IHS Markit analysis.
“Progress in growing the share of low-carbon generation, such as solar and wind, in the global power mix also brings a particular set of challenges—namely intermittency,” said Sam Wilkinson, associate director, clean technology and renewables, IHS Markit. “Improving cost-effectiveness of energy storage, particularly batteries, will be key to providing needed flexibility to balance this supply of electricity with demand.”
How we get there
IHS Markit expects that the biggest contributor to falling battery cell costs throughout the coming decade will be reductions in manufacturing costs through larger factory sizes and improving economies of scale. Reductions in material costs by improving efficiencies and adopting lower cost cathode compositions, and improvements in battery energy density are also expected to play a role.
LFP already there
Among the three major Li-ion battery cells—Nickel Manganese Cobalt (NMC), Nickel Cobalt Aluminum (NCA) and Iron Phosphate (LFP)—LFP has already fallen below the $100/kWh threshold in 2020.
All three types are expected to be below the $100 mark by 2024. LFP will remain the lowest cost option throughout the next 10 years. However, NMC and NCA will continue to command a majority share of the automotive and transport sector on account of their higher energy density.
Have you checked out our YouTube page?
We have a ton video interviews and additional content on our YouTube page. Recently we debuted Power Forward! -- a collaboration with BayWa r.e. to discuss higher level industry topics as well as best practices / trends for running a solar business today.
Our longer running side project is The Pitch -- in which we have awkward discussions with solar manufacturers and suppliers about their new technology and ideas so that you don't have to. We've discusses everything from residential rail-less deck attaching and home solar financing to large-scale energy storage value stacking and utility-driven new home solar + storage microgrids.
We also post our Project of the Year announcements there! Interviews with this year's winners will be up starting the week of Nov. 8. Head there and subscribe today to stay on top of all this extra stuff.
